Signage not very clear. RV camping is in lot #3 in the northeast corner of the property, between the back side of the Casino and the gas station. If coming east from 41 freeway, go past the main entrance, turn right at the gas station, and turn right into the backside of the lot. There is a shuttle to take you to the casino 24 hours per day, running frequently but you can call for a pick up. The walk is longer than it looks because you have to go all the way around (they don’t let cut in behind). Lot was empty except for our camper and several semis. Somewhat loud because of truck generators and early morning construction (seems to be an ongoing thing). Did not bring our genetator thinking we could not use at night but since the trucks were, we could have kept cooler using AC instead of battery operated fan! No hook-ups. No one bothered us. Security drove by regularly. Overall, a good stay - can’t beat the price but bring ear plugs and you will be good to go!

2nd visit this year. Construction going on in 2nd car park but lots of room in 3rd for RVs and trucks. Fairly empty parking area given that it was Thanksgiving. Buffet was excellent but $26 with no discount for seniors. Shuttles and security came by frequently and lighting is good. A new Service station has reasonable rates $3.31 for diesel and sells convenience items. The sewage pump station for the hotel still makes a whine when activated so best to park some distance away from it. This is a good stop in central California, out in the country - I stayed for 3 nights and will come again. Added "attractions of the parking lot were a small pack of friendly pit bull dogs and a dirt bike enthusiast who kept roaring up an adjacent road doing wheelies and making a lot of noise.
I won $1 at a slot machine and gave it to the shuttle driver as a tip

Stayed here overnight while travelling to Palm Springs. RV parking is in Lot 3, there are RV painted lines on the far East side of the lot. More trucks than RV's (3 including ours). There is construction going on in Lot 3 but there is lots of room for parking. Security passed by at least once and hour but never stopped to talk, don't know if there are any rules never seen any posted.

Walked through the casino and had a look at the buffet but wasn't tempted by either.

Tachi Palace Casino (N36 14.214 W119 45.396) Lemoore, CA
Took about 4 hours to drive here from Cache Creek, plus a stop at Joe’s Truck Stop, on I-5 at Westley, south of Stockton, to eat at a Denny’s restaurant. This is a very good place to pull in for fuel or food/truck wash and other services I have yet to investigate. There is plenty of room to turn around, access the pumps or park.
Tachi had a big band event happening, so the shuttle people told me parking would get crowded. This never really happened as I was pretty well the only RV in the whole parking area on arrival. A couple more came along later but not exactly crowded. Parking lanes being painted for regular cars, I straddled a white line to take two full parking slots, thus having plenty of room for my slides. There is a pump station for, presumably, casino sewage, in the RV lot. This emits a high whine and would be uncomfortable if one parked closely adjacent to.
At this casino, visitors appeared to be mostly Indian, whereas at Cache Creek, Asians were the dominant species.
The buffet, which I rate “quite” good, as opposed to “exceptional”, had no discounts for seniors or for Player’s Card holders and therefore cost the full $20. The Player’s Card, in fact, doesn’t seem to do a whole lot other than accumulate “points” for something that I couldn’t determine
Golf cart shuttles circled the RV parking lots like sharks and one could catch a ride anytime by waiting 5 minutes, or not at all. The walk to the casino is not far. In addition, during the day bicycle security patrols are a frequent sight so I felt that this was quite a safe place. At this time, construction is going on to build a new fuel station - this slated for completion in Spring 2017
Gambling is spread over at least two floors with the buffet being up on the second floor. This is another huge place with hotel and conference facilities and is located out in the country a few miles from Lemoore, off Hwy 198/18th St

Construction fences on most of lot 2 and part of lot 3. Still lots of parking space in lot 3. Frequent golf-cart style shuttles, but it's not much of a walk without. Construction noise and trucks durring the day.

No non-smoking gambling, players club gives same discount as senior at the buffet and no free play or joining perks.
